Organic fertilizer capable of expanding water-holding capacity capacity of soil, and preparation method thereof

Abstract

The invention discloses an organic fertilizer capable of expanding the water-holding capacity capacity of soil. The organic fertilizer comprises the following raw materials by weight: 40 to 50% of oilresidues, 20 to 25% of crop straw, 1 to 3% of ginkgo leaves, 5 to 8% of domestic fungus residues, 10 to 15% of livestock manure, 1 to 4% of calcium magnesium phosphate fertilizer or ground phosphaterock, 2 to 5% of traditional Chinese medicine residues, 1 to 3% of lime or plant ash, 0.5 to 1% of Bacillus amyloliquefaciens, 1 to 3% of zinc sulfate, 1 to 3% of ferrous sulfate, 2 to 5% of active carbon or collagen and 2 to 5% of polyacrylamide, summing to 100%. A preparation method for the organic fertilizer comprises the following steps: stacking the above raw materials for decomposing and fermentation, and then successively carrying out sieving, drying, crushing, granulating, drying and packaging. The organic fertilizer provided by the invention can effectively improve soil structure, increase the organic matter content of soil, fertilize soil, enhance the availability of soil nutrients, improve the quality of agricultural products, stimulate plant growth, purify soil environment, enlarge the water holding space of soil, retain water and inhibit evaporation.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to an organic fertilizer for increasing soil storage capacity and a preparation method thereof, which is used for comprehensive utilization of waste such as oil residue, crop straw, livestock manure, edible fungus residue, traditional Chinese medicine residue and other wastes. A new way to develop new products from waste to wealth. Background technique [0002] 1. The status quo of organic fertilizer in my country [0003] Organic fertilizer is an extremely important link in traditional agriculture in our country. In agricultural production, in addition to obtaining food, oil, fiber, meat, eggs, milk and other products, human beings also produce a large amount of agricultural by-products such as orange stalks, cakes and manure. These agricultural by-products are all used as fertilizer, fuel, feed and industrial raw materials, forming a good circular economic model. This circular economic ...

Problems solved by technology

The "rich ingredients" contained in these traditional Chinese medicine dregs are extremely valuable for development and utilization; at present, some companies have sold the dregs of traditional Chinese medicine as products. The dregs of traditional Chinese medicine are dried and then crushed to be sold as organic fertilizer raw materials. According to the data retrieval conducted by the applicant, there are very few research reports on the dregs of traditional Chinese medicine, even fewer successful examples, and most of them are exploratory preliminary studies.
